10- For the quadratic function f(x) = - 2x2 + 2x - 5. answer parts (a) through (f). (a) Find the vertex and the axis of symmetry of the quadratic function, and determine whether the graph is concave up or concave down. The vertex is |:|. (Simplify your answer. Type an ordered pair, using integers or fractions.) What is the equation of the axis of symmetry? The axis of symmetry is |:|. (Type an equation. Use integers or fractions for any numbers in the equation.) Is the graph concave up or concave down? O Concave up 0 Concave down (b) Find the y-intercept and the xintercepts, if any. Select the correct choice below and, if necessary, ll in the answer box to complete your choice. 0 A. The xintercept(s) isiare |:|. (Type an integer or a simplified fraction. Use a comma to separate answers as needed.) 0 B. There are no xintercepts. What is the y-intercept'? Select the correct choice below and, if necessary, ll in the answer box to complete your choice. 0 A. The y-intercept is |:|. (Type an integer or a simplified fraction.) 0 B. There is no yintercept. (c) Use parts (a) and (b) to graph the function. Use the graphing tool to graph the function. (d) Find the domain and the range of the quadratic function. The domain of f is |:|.
